Description
Root cause is https://github.com/pandas-dev/pandas/issues/41575
In the Series groupby case proxy generation raises an error. In the DataFrame case it produces a Series, when it should produce a DataFrame with the expected columns.
Imported from Jira [BEAM-12366](https://issues.apache.org/jira/browse/BEAM-12366). Original Jira may contain additional context.
Reported by: bhulette.
Contributor guide
Research direction
Start by reading the linked pandas issue 41575 and reproducing GroupBy.describe for both Series and DataFrame cases. Done means Series groupby proxy generation no longer raises an error, while the DataFrame case returns a DataFrame with the expected columns.
